DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] like Figures 1-9 As shown, the Bucky structure of the switchable flat-panel radiographer includes a housing 10, to which a drawer board assembly 20 is detachably connected in a horizontal sliding manner. A placement board assembly 30 for placing a flat panel is mounted on the drawer board assembly 20 via a rotating assembly 40, and under the action of the rotating assembly 40, the placement board assembly 30 is rotated and switched between 0° and 90° limits; the placement board assembly 30 includes a fixedly mounted flat panel bottom plate 1 31 and a position-adjustable flat panel bottom plate 2 32. In this embodiment, the existing structure is adopted for restricting the flat panel after it is placed on the flat panel bottom plate 1 31 and the flat panel bottom plate 2 32.

[0029] The rotating assembly 40 includes a rotating base 41 and a positioning turntable 42. The rotating base 41 is installed on the drawer board body 21 of the drawer board assembly 20. Two limit blocks 48 are installed on the rotating base 41. The middle part of the positioning turntable 42 is rotatably installed on the rotating base 41. One end of the positioning turntable 42 has at least one limiting protrusion 42a. The limiting protrusion 42a is arranged between the two limit blocks 48, and the limiting protrusion 42a can be abutted against the limit blocks 48. The other end of the positioning turntable 42 is connected to the flat bottom plate 31.

[0030] The placement plate assembly 30 includes a linear guide rail 36, a slider 35 and a guide rail fixing block 37. One end of the linear guide rail 36 is connected to the flat base plate 1 31, and the other end of the linear guide rail 36 is connected to the guide rail fixing block 37. The slider 35 is slidably connected to the linear guide rail 36. The flat base plate 2 32 is installed on the slider 35. The flat base plate 2 32 also has a plunger 1 34 that cooperates with the guide rail fixing block 37.

[0031] Two micro switches 47 are mounted on the rotating base 41 and match with the limiting protrusion 42a.

[0032] In this embodiment, there are two limiting protrusions 42a, one located at the upper position, which can cooperate with the limit block 48 and micro switch 47 located at the upper part; and the other located at the lower position, which can cooperate with the limit block 48 and micro switch 47 located at the lower part.

[0033] Two positioning recesses 42c are provided at one end of the positioning turntable 42. A positioning seat 46 is slidably connected to the rotating base 41. A positioning member 45 is provided on the positioning seat 46, and the positioning member 45 can be inserted into any positioning recess 42c. An elastic support member 44 is also provided between the positioning seat 46 and the rotating base 41.

[0034] A micro switch 2 43 is also installed on the positioning turntable 42 .

[0035] Two locking blocks 22 are installed on the drawer board body 21 , and a second plunger 33 matching with the locking blocks 22 is installed on the flat bottom plate 1 31 .

[0036] One end of the linear guide rail 36 is connected to the flat bottom plate 31 through a guide rail pressing block 38.

[0037] The drawer panel assembly 20 further includes a handle 23 , which is connected to the drawer panel body 21 .

[0038] In this embodiment, a 14-inch tablet or a 17-inch tablet is placed on the flat bottom plate 1 31 and the flat bottom plate 2 32. The linear guide 36, the slider 35, the guide rail fixing block 37 and the plunger 1 34 cooperate to adjust the position of the flat bottom plate 2 32. When installing a 14-inch tablet, the flat bottom plate 2 32 is adjusted close to the flat bottom plate 1 31 and the plunger 1 34 is inserted into the guide rail fixing block 37. When installing a 17-inch tablet, the plunger 1 34 is pulled out and the flat bottom plate 2 32 is adjusted away from the flat bottom plate 1 31. When the flat bottom plate 2 32 moves to the maximum limit position, it can just fit into the 17-inch tablet. inch tablet; by rotating the tablet bottom plate 1 31, the positioning dial 42 rotates, and the limiting protrusion 42a on the positioning dial 42 abuts against the corresponding limit block 48. At the same time, the positioning member 45 is snapped into the corresponding positioning recess 42c, which plays a role in prompting the position; then the plunger 2 33 is inserted into the corresponding locking block 22 to lock the position of the tablet bottom plate 1 31; after switching it, the drawer board assembly 20 is pushed back into the casing 10; the micro switch 2 43 can identify whether the tablet is on the tablet bottom plate 1 31; of course, in practice, two other tablets of different sizes can be installed by making adjustments.

[0039] The rotation center is not the center of the 17-inch tablet or the 14-inch tablet. The actual rotation center is in the middle of the horizontal center line of the 14-inch and 17-inch tablets, and is equidistant from both ends. Only at this position can the horizontal or vertical exposure center of the 14-inch tablet be closer to the human chin and be on the same horizontal line as the 17-inch tablet when horizontal.

[0040] In summary, the present invention uses a set of rotating structures to enable the entire placement plate assembly 30 to rotate 90°. Because the 14-inch tablet is not square, it needs to be rotated 90° to meet the shooting requirements when shooting; the placement plate assembly 30 for placing the tablet is located above the rotating structure. It must meet the shooting requirements of the 14-inch tablet and cannot be rotated around the center. There are position requirements when selecting the rotation center, which can be adjusted according to actual needs.

[0041] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0042] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
